COMPRESSION CONNECTION PART OF LOW SAG ELECTRIC WIRE

摘要

PROBLEM TO BE SOLVED: To raise gripping force of aluminum strand layers 3A and 3B by an aluminum sleeve 7, relating to a compression connection part of a low sag electric wire, including: a low sag electric wire 1 which contains a steel core strand 2 at a center, and the plurality of layers of aluminum strand layers 3A and 3B configured by twisting together aluminum element wires having a segment shape in cross section on its outside, and is provided with a gap provided between the aluminum strand layer 3A at an inner most layer and the steel core strand 2 at the center; a steel sleeve 6 to which the steel core strand 2 is compression-connected; and the aluminum sleeve 7 to which the aluminum strand layer 3A and 3B are compression-connected.SOLUTION: End parts of the aluminum strand layers 3A and 3B in a plurality of layers are step-peeled so that an end part of an aluminum strand layer 2A at an inner most layer is exposed, and a metal collar 10 is interposed between the exposed aluminum strand layer 2A in the inner most layer and the aluminum sleeve 7, for compressing of the aluminum sleeve 7, thus, a compression force is separately applied to the aluminum strand layers 3A and 3B in respective layers.
